本项目研究低表面亮度星系的恒星形成指标间的相互关系以及气体与恒星形成的关系。2013-2018年间，我们观测处理完成了468个低面亮度星系的Halpha成像样本以及观测了169个正常星系的Halpha图像做为低面亮度星系的对比样本。基于低面亮度星系和正常星系的Halpha图像，计划开展2项内容。（1）结合GALEX和WISE数据，研究低面亮度星系的Halpha光度与紫外、红外光度之间的相关性，进而实现不同恒星形成指标的相互标定。（2）重新处理Halpha图像，探究低面亮度星系的恒星形成区是否符合经典的气体与恒星形成关系(Kennicutt-Schmidt Law)。

This project studies the interrelationships among various star formation tracers of the low surface brightness galaxies (LSBGs) and the relationship between gas and star formation in LSBGs. From 2013 to 2018, we observed and processed the Halpha images of 468 LSBGs, and 169 normal galaxies as comparative sample. Two research contents are planned: (1) Searching for the correlation among Infrared, Ultraviolet and Halpha luminosities in our LSBG sample by combining their GALEX, WISE and Halpha images. (2) Reprocessing the Halpha image to explore whether the star formation regions of LSBGs follow the empirical relation between the gas density and star formation in a given region (Kennicutt-Schmidt Law).
